How to achieve the following flow in android app?

My app receives a push notification and one of its activity gets launched. Now,

Press home

Relaunch app from home screen(app launched with main activity)

Press back

eg Activities A-->B--->C

Notification launches 'C'

Press HOME on C

Relaunch app ('A' gets launched)

Press back

Now the weirdness appears, pressing back is taking the user to same activity that was launched on notification click, in this case its taking the user to 'C'

I do not want this flow..pressing back key on main activity should exit the app.

any help?

Override the back button to do your desired function:

    @Override
public void onBackPressed() {
    Your function here.
    super.onBackPressed();
}

And also you can add flags to your intent while calling respective activiies:

 1.FLAG_ACTIVITY_NO_HISTORY

用这个-

 @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {      
    if ((keyCode == KeyEvent.KEYCODE_BACK))
    {

    finish();//do ur task
    }
    //same check for home screen key and do u task

    return super.onKeyDown(keyCode, event);
    }
